Extinction of life on Earth
through Global Warming

Things r far worse than what u thought

CO2 TRIGGERS METHANE HYDRATES TIPPING POINT
Man-made CO2 now traps so much solar heat that Arctic tundra, which was frozen for tens of thousands of years, is melting. Tundra covers about 20% of the earth’s land surface. A few years ago, it was found that, beneath the Siberian Arctic tundra permafrost, lies 400 billion tons (gigatons) of frozen methane locked in methane
hydrates. Last year, scientists detected Arctic methane bubbling out from the tundra five times faster than previously measured.

For the past 420,000 years, Earth’s atmospheric methane has remained between 450-750 ppb (parts per billion). Methane now exceeds 1750 ppb, more than double the previous maximum. Here is the danger: methane has 21 times more heat-trapping effect than carbon dioxide.

Freshly released methane traps more of the sun’s heat, that melts more tundra, that releases more methane, that traps more heat in runaway global warming. Releasing only 9 of the Arctic ’s 400 gigatons of frozen methane would exceed a hidden tipping point that starts a heating avalanche. Once started, it cannot be reversed!

The most conservative strategy, in the United Nation’s IPCC AR4 (Intergovernmental Panel on Climate Change Fourth Assessment Report) last November, proposes a greenhouse gas emissions reduction that would stabilize Earth’s temperature rise at 2 degrees Centigrade above pre-industrial levels. The lifestyle changes needed to stabilize at 2 degrees are widely regarded as politically and economically unfeasible, and yet, a 2 degrees rise already guarantees that the 9 gigatons of Arctic methane will be released.

This is because 2 degrees is a global average, but that 2 degrees is not evenly distributed. Temperatures over the cool oceans won’t rise much at all, whereas temperatures over the land will get hot enough to stop crop pollination and force trees to change from CO2 absorbers to CO2 emitters!

An increased global average temperature of 2 degrees means an 8 – 10 degrees rise exactly where the frozen methane waits in the arctic regions. Reflective snow melts, exposing land or water to absorb much more of the sun’s warmth. Civilization as we know it will vanish under an onslaught of storms, famine, drought, disease and conflict. Likely two thirds or more of humankind will be dead in our lifetimes! National governments and economies will end and life as we know it will, abruptly, halt.

This is not written to scare people, although it will, but to call
people to action on behalf of everything that they love on the Earth, for their children and grandchildren. How many will find life blighted?
How will they be affected personally if this scenario comes to pass? If there
was ever a time to take personal actions, that time is now.

PLease forward to all
